CONCRETE AND WQD FLOOR CONSTRUCTON DEVKGE.

` a specification. l

The object of my invention is to provide a concrete and wood floor construction device of simple and inexpensive construction. Considerable' diiiiculty is involved in laying a wood floor "on a concret-e base, and it is my purpose to provide a construction, .whereby such a iioor can be laid on a concrete-base with the parts accurately placed in the 4proper:position and ata minimum expense. g

.fWith theseafnd other objects in view, my

invention consists in the construction, ar`

rangement and combination of the various f parts of my fde'v-ice, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims,

and illustrate? in the accompanying drawings in wlri'ct 1: y

ignre l shdws a detail, sectional, perspective view of aiiioor construction embodying my inwention;` l

Fig. 2 shows s, perspective view of the means for fastening the sleepers to the concreteV base; and

lFig. 3 showsfary imilar view illustrating the arrangement o the fastening Adevices tor shipping and storage.

*Ordinarily ,in laying' a wood iioor on a concrete base, the concrete base is laid, then sleepers are placed in position on the floor and anchored fromthe ceiling,so as to hold them in place. Nails or the like are driven in the sleepers, having preferabl one beveled side edge, and an additiona layer of thin concrete is poured between the sleepers for anchoring them.

This is a slowvand expensive process, which I have sought to avoid by means of i my structure herein set forth.

In the accompanying drawings, I fhave.

used the. reference numeral l0 to indicate generally a concrete base. Properly spaced on the concrete base are sleepers 1l.

For fastening the sleepers 1l to the base, I have provided -the followino' means:

I provide a strip of metal?, which is bent to :torni a central, horizontal member-12, from which there extends downwardly arms or portions 13, the lower parts of which are crimped, as illustrated at A. F rom the lower ends of the arms or portions 13, the strip is bent ,upwardly on each side, as at 4l, and crimped, as shown :tor instance in Fign 2.

The stripis long enough, so that the ends C extend upwardly substantially above. the central portion 12. The ends C are pro vided with holes 14. to receive nails.

For storage or transportation, the ends C are bent over the member l2 and `overlap each other, as illustrated .in Fig. 3.

When the concrete base l() is laid, and while the concrete is still soft, the ends A and B are forced down into the concrete, as shown in Fig. l, and the concrete allowed to set. The .bending overfof the ends @as in Fig. 3, permits free use of the concrete door without interference by the fastening` devices until' such time as it is desired to lay the wood floors. f

At the proper time the ends C are bent up to vertical position, as shown in Fig. 2, from their positions shown in full lines in Fig. 3, and the sleepers ll are laid between the spaced end members C, as shown in Fig. l, and secured thereto by means of nails driven through the holes 14e into the sleepers.

By the use of the term crimped herein, I intend to include corrugations or an; forni of device having projecting elements 1 r receiving proper anchoring in the concrete.

I The sleepers will thus be accurately placed and rigidly held in position with relation to HElSSUED Specification of Letters Patent. p Einigung@ Jun@ 141:7 iigg Application filed November 1, 1920. Serial No. 421,620.

the base l0. The iioorinp;- may be then nailed to the sleepers in the ordinary way.

By the construction herein shown, it will be seen that I am enabled to accurately and the sleepers from their proper position, and

l save the use of material necessary to provide a layer of concrete extendingN from the base l0 part way up the sleepers 1]..

also greatly reduce the weight ot the concrete base, thereby making it possible to use less material and lighter steel through the entire construction, where a buildinga oir' several stories is under construction.

It will be seen that my process involves the pouring of a concrete base, the forcing therein while soft of the fastening device, having the member 12, which serves as a stop member, the allowing of the concrete to set, the 'laying of the sleepers and fastening them to the fastening devices, and the laying of the floor on the sleepers. i y

Changes may be made in the details of the construction of my Hoor structure and in the steps in the practicejof my process, without departing from the spirit and purpose of-my invention, and it is my intention to cover by imy claims, any modiedfonns of structure or use of -mechanical equivalents, or' any lvariatn'yns 1n the stepsof the process', which l may be included within their scope.

AI claim as my invention:

1. A support for concrete and ivo-od loor "construction, comprising a'single'piece of bers, and adapted to receive a sleeper between th'em. 2. ln' a device of the class described, a fastener device comprising a single strip of .material having a central member` with bent down parts, crimped and rebent upwardly from the lower. ends of the bent down parts, and projecting upwardly above said central member, and provided with openings for fastening said last-described parts to sleepers.

3. In a device of the class described, a fastener device comprising a single strip of material having a central member with bent down parts at the edges thereof, having their lower parts crimped and reebent upwardly from the low-er ends of 'said downwardly eX- tending partscrimped at their lower parts andV proj ecting upwardly above said central member' and provided with openings for fastening said last-described parts being made of material, which can be bent over said cer tral member for reducing the bulk of said device for transportation and storage.
